Nutritional evaluation of sprouted barley grains on agricultural by-products on performance of growing New Zealand white rabbits

摘要

Sprouted barley grains was produced using agricultural by-products as bedding media and the treatments were hydroponic barley with 0.5% urea (HBU), sprouted barley on rice straw with 0.5% urea (SBRSU), sprouted barley on wheat straw with 0.5% urea (SBWSU), sprouted barley on bean straw with 0.5% urea (SBBSU), sprouted barley on rice straw with 100 g poultry dropping (SBRSPD) and sprouted barley on rice straw with 100 g animal faeces (SBRSUAF). Three digestibility trials were conducted using mature male New Zealand White (NZW) rabbits with an average body weight of 2.5 kg and aged 8 months to evaluate sprouted barley grains (HB, SBRS and SBBS). A total of 40 NZW rabbits at 8 weeks of age (16 males with 1039±36.65 g live body weight (LBW) and 24 females with 934.75±39.78 g LBW). Rabbits in the 1st group were fed commercial rabbit diet (CRD) served as control (G1). While, 30% of CRD was replaced by HB (G2), SBRS (G3) or SBBS (G4), respectively during feeding period from 8 to 16 weeks of age.
